Custom font for Android listview

Question

I have a custom font for my android activity.

MainActivity.class

    private void initControls() {
    // TODO Auto-generated method stub
    header = (TextView) findViewById (R.id.tvAccommodations);
    lv = (ListView) findViewById (R.id.lvAccommodations);
    text = (TextView) findViewById (R.id.textView);

    Typeface tf = Typeface.createFromAsset(getAssets(),
            "fonts/heartbre.ttf");
    header.setTypeface(tf);
    text.setTypeface(tf);



    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
                    R.array.abra_hotel, R.layout.custom_list_text);
            lv.setAdapter(adapter);
            header.setText(value);

custom_list_text.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/list_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="18sp"
android:textStyle="bold"
android:text="@string/app_name"
android:paddingLeft="6dip" />

Android throws NullPointerException. Why is it so? Any help is appreciated. Thanks.

Solution 1

Here is the custom adapter class and the constructor

class CustomAdapter extends ArrayAdapter<CharSequence>{

    Context context; 
    int layoutResourceId;    
    CharSequence data[] = null;
    Typeface tf; 

public CustomAdapter(Context context, int layoutResourceId, CharSequence[] data, String FONT ) { 
    super(context, layoutResourceId, data);
    this.layoutResourceId = layoutResourceId;
    this.context = context;
    this.data = data;
    tf = Typeface.createFromAsset(context.getAssets(), FONT);
}   

Put the font you want to use in your assets folder and fill your listview like this:

listAdapter = new CustomAdapter(this, R.layout.custom_list_text, R.array.abra_hotel, "name_of_font.ttf");

you can't apply font directly to listview and you need to create custom adapter for listview and change it font for more details click below stack post it's already discussed.

It is not working for my adapter, here is the SO: stackoverflow.com/questions/21439707/…

You created a property called tf and set a Typeface to it, but tf isn't assigned to anything. How does this code set the font of the item renderer?

I put font sin "src/assets/fonts/myfont.ttf" and passed into the adapter "fonts/myfont.ttf" and it worked. Thanks!
